the mean and population-safe protein requirements were estimated to be 0.93 and 1.2 g · kg−1 · d
-
diet containing 0.90 g · kg−1 · d−1 was at or above physiologic protein requirements for sedentary men
-
The current EAR recommendation and RDA for protein are 0.66 and 0.80 g · kg−1 · d−1, respectively. We believe that these recommendations are tentative because no long-term studies have suggested that these values would maintain nitrogen balance along with lean body mass, muscle mass, serum protein concentrations, immunity, functional capacity etc

a series of long-term balance studies (67-69) showed that intake of the proposed safe allowance of 0.57 g (70) egg protein resulted in negative nitrogen balance, loss of lean body mass, and deteriorating serum protein and transferase values unless additional energy or nonessential nitrogen was supplied

The results of the present study suggest that the current EAR recommendations (0.66 g · kg−1 · d−1) and RDA (0.80 g · kg−1 · d−1) for protein are underestimated at 29% and 33%, respectively
